This invention has I struction of a pipe for its objects the conforsmoking tobacco wherein the nicotine shall be practically whollyeliminated from the smoke on its way to the users mouth; and for keepingthe exterior of the pipe comparatively cool.

To these ends, I have devised the construction hereinafter set forth andillustrated in the drawings forming'a part of this specification, and inwhich Figure 1 is a side sectional view of a pipe embodying one form ofmy invention. Figure 2 is a horizontal section of the same on the line22 in Figure 1. Figure 3 is a side sectional view of another form of theinvention.

The construction illustrated in Figs. 1 and 2 is in two parts, the bowl1 and the body 2. The body has a cistern 3 into which the bowl descends,and an annular chamber 4 in its wall into which the pipe stem 5 opens.The upper part of the bowl 1 is radially enlarged, as at 6, and threadedto screw into the upper end of the inner wall 7 by which the annularchamber 4 is inwardly bounded; and the bowl is further provided with aflange or cap 9 enclosing the entire wall of the body 2. Below theshoulder 6, the bowl is spaced fro the wall 7 and also from the floor ofthe cistern 3; and is provided with an opening through the bottom, ofthe smoke and vapors from the burning tobacco down into the cistern 3.

The oil of nicotine dripping through the opening 10 collects in thecistern, but the smoke rises up between the exterior of the bowl 1 andthe wall or partition 7, until itreaches and passes through a hole 11 inthe wall 7 into the annular chamber 4. To reach the pipe stem 5, whichopens from the opposite side of the body 2, the smoke must move half-wayabout the wall 7; and not only so, but it must first enter the annulartube 12 through an opening 18, and traverse the same until it can findits exit through an opposite hole 14 to permit it to reach the pipestem.

I prefer to make the tube 12 of some inexpensive and more or lessfibrous material similar to blotting paper, in order that it may ab- -1with a multiplicity of as at 10, for the passage P sorb any remainingnicotine precipitated therein.

Thus disposed, three different places are provided for the collection ofthe nicotirie; first, the cistern 3; the bottom of the chamber 4, andthe annular tube 12; thus making sure that practically none of thenicotine can reach the mouth of the smoker. I

For ensuring that the outer surface of the pipe shall be kept frombecoming uncomfortably hot, I provide the outer wall of the bodyvertical passages 15 reaching entirely through from the bottom and upthrough the flange 9. To make sure that the passages through the flangeshall communicate with those in the body, an annular groove 16 isformedeither in the flange or in the body, but preferably in the latter,cutting into the ends of the passages 15.

In the construction shown in Fig. 3, the pipe is made in three parts,the cistern 20 being separable from the body 21 and internally threadedat 22. The bowl 23 is provided with a radially projecting flange 24threaded to mesh with the threads 22, and by means of which it is heldin place with its top flange h 25 seated upon the body 21. Intermediateof the top and bottom of the bowl are two spiral flanges 26 adapted toreceive the smoke at one 'oint and to deliver it to the stem 28 at adiametrically opposite point.

To enable the, products of combustion to reach the cistern 20 fromwithin the-bowl, the floor of the latter is given a hole 27, preferablynear one side and sloping farther from the center at its lower end topresent the products close to the wall of the cistern. A lip 29 is alsoprovided for the lower end of the hole to ensure against any-liquidadhering to the under surface of the bowl and creeping along the same.

Up through the flange 24 diametrically opposite the hole 27 is a passage30, whereby the smoke from the bowl passes downward through the hole 27,across the cistern, and up through the hole 30 into the lower portion ofthe space about the bowl, and thence through the space between thespiral flanges 26 to the pipe stem; thus ensuring that no nicotine canreach the mouth of the smoker. 109

I After suitable intervals of use, the pipe is to body for insuringcommunication between be taken apart and the accumulations of nicosaidapertures and a consequent open line of tine and other products of theconsumed circulation at different points around the wall tobacco emptiedout from the parts. of the combined body and cistern.
